alleryThe refractive index for a pair of media is independent of the:
AAngle of deviation
BAngle of incidence
CAngle of elevation
DAngle of departure
Answer & Solution
Correct answer: B. Angle of incidence
1. The index is a property of the two media themselves.
2. It is a characteristic of the pair of media and depends on wavelength.
3. But it is independent of the angle of incidence.
